1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.


Density of Coarse Aggregate Aggregate which occupy nearly 80 to 85 % volume of concrete are most important part of the concrete or RCC. However, it is well recognize that physical, chemical and thermal properties of aggregate substantially influence the properties and performance of concrete.


Pennsy Supply is the largest producer of aggregate in central Pennsylvania, producing more than nine million tons every year consisting of primarily crushed stone, sand …


Background Specific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73. aggregate and asphalt binder volumes are diffucult to measure directly.


Here, for coarse aggregates, the standard test method has been explained in ASTM C 127(AASHTO) and for fine aggregates, the standard test method has been explained in ASTM C 128 (AASHTO). [3] The relative density of an aggregate can be determined on an oven-dry basis or a saturated surface-dry (SSD) basis.

The coarse aggregate particles are usually crushed stone or crushed gravel, and the fine aggregate particles are ...


1 SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85 GLOSSARY Absorption: The increase in weight due to water contained in the pores of the material. Bulk Specific Gravity (also known as Bulk Dry Specific Gravity): The ratio of the weight in air of a unit volume of aggregate at a stated temperature to the weight in air of an equal volume


5.1 Relative density (specific gravity) is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles – also referred to as the absolute volume of the aggregate. It is also expressed as the ratio of the density of the aggregate particles to ...


coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influ- ... concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. ... The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following

FORNEY LP is the worldwide leading innovator of scientific testing, measuring and processing instruments for the concrete, soils and asphalt industries.


cylindrical metal measure used for bulk density and void test of aggregate Sample Preparation. Take the required amount of test sample form the bulk sample using any sample reduction method.; The test is normally carried out on dry material, but when bulking tests are required, material with a given percentage of moisture may be used.


For the preparation of economical concrete mix on should use largest coarse aggregates feasible for the structure. IS-456 suggests following recommendation to decide the maximum size of coarse aggregate to be used in P.C.C & R.C.C mix.


For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement. Thus bulk density also depends upon the degree of packing.


High Density Aggregate Our high density aggregate is an environmentally and non-toxic product produced from high-quality natural magnetite. We offer fine grade and coarse grade high density aggregate.

Jun 09, 2005· The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).


Coarse aggregate is also described by its bulk density, which is a property that can easily be tested in the laboratory. The standard testing procedure for this is the American Society of Testing ...
